Abstract

This paper deals with the effect of fillers and additives on the mechanical properties of pultruded composites. Six materials with varying filler and low profile additive (LPA) content have been manufactured by pultrusion using E-glass fiber reinforcement roving in a general purpose unsaturated polyester resin. The materials were pultruded in the form of a 50x6.4 mm rectangular cross-section profile. The mechanical tests consist of three-point-bending tests according to the ASTM D2344 Standard for short beam shear tests and the ASTM D739 Standard for flexural tests. Additional tests were performed at other span-to-depth (L/h) ratios varying from 5 to 24. The test results are analysed to serve two different objectives. The f
